Motorola 68010

A {microprocessor} from {Motorola}. It was the

successor to the {Motorola 68000} and was followed by the

{Motorola 68020}. Some instructions which were previously

{user mode} were made {system mode}, which necessitated

patches to a few programs.

The 68010 also had a primitive {cache}. The DBxx instructions

(decrement and branch) were cached, along with a few previous

instructions. Small loops could thus execute from the cache

directly.

At one time there was a 68010 variant that was pin-for-pin

compatible with the 68000. Early {Amiga} hackers replaced

their 68000s with 68010s in order to get a small performance

increase.
